Definitions

  • This invention relates to a method of laying paving, in particular of placing units of paving stones or bricks previously arranged in a selected pattern in a road surface, said method comprising engaging such a unit by clamping at opposite edges and putting it down on a prepared sand bed or like substrate in contiguity with previously laid road surface components while pressing the same into contact with such road surface components, and with a downward force to be exerted on the upper surface of said unit.
  • the border stones or bricks of a unit experience friction from each clamping strip or jaw of the grab, owing to which they do not fail vertically downwardly, but tend to tilt, the row or rows of border stones or bricks contiguous with the ready road surface component will be additionally prevented from falling vertically downwardly owing to the great friction they experience from the ready road surface component as they are moving downwards.
  • the frictional forces referred to are now prevented from tilting the border stones or bricks concerned because these border stones or bricks remain clamped between, on the one hand, the road surface already laid and, on the other hand, the middle stones or bricks of the unit or group throughout their path of movement right down to the substrate, and are thereby pressed positively downwards.
  • a downward force can be exerted on each row of border stones or bricks, and this per row of border stones or bricks independently of the exercise of force on the other rows of border stones or bricks.
  • the invention also relates to a grab comprising a frame including suspension means for attachment to a jib of a swivelling crane, and at least one pair of opposite clamping strips cooperating for clamping a unit or group of stones or bricks previously arranged in a pattern, one clamping strip being arranged so as to be movable, and the other being rigid relatively to said frame, said frame further carrying a holddown mechanism operative vertically downwardly, as disclosed in German "Offenlegungsschrift" No. 1,534,201.
  • this grab is characterized in that said hold-down mechanism is operative along at least the inside of said movably arranged clamping strip.
  • a simple and effective hold-down mechanism comprises one or more hold-down strips each biased downwardly by spring means, said spring means being secured to a tensioning frame movable relatively to the carrier frame between a passive and an active level.
  • the tensioning frame For picking up a unit or group of stones or bricks the tensioning frame is moved upwards, so that the apparatus can be lowered onto a stack of units of stones or bricks without being hindered by the hold-down strips.
  • the tensioning frame When the uppermost unit has been engaged, the tensioning frame is moved to the lower, active position, as a result of which the hold-down strips are pressed down on to the respective rows of border stones or bricks, and can force these downwardly as soon as the lateral clamping has been sufficiently released.
  • the grab is provided with a supporting rail secured to the carrier frame along the outside of at least one of the clamping strips and at least one supporting plate spaced from said supporting rail, the levels of said supporting rail and of said supporting plate being adjustable so as to enable them to function as level positioning means relative to paving already laid and relative to the sand bed or other substrate.
  • a hand rail may be provided for maneuvering the grab.
  • the suspension means whereby the carrier frame is suspended from the swivelling crane preferably includes a combination of universal joint means and freewheel joint means.
  • the correct horizontal position may be found by maneuvering by means of the hand rail, and when the grab is further lowered it comes to rest on the supporting rail and the supporting plate. Owing to the freewheel clutch, further downward movements of the crane jib can no longer adversely affect this position found.
  • FIG. 1 shows a paving machine including the grab according to the invention
  • FIG. 2 is a plan view of the grab, with a number of parts, such as the suspension means, being omitted for clarity; and
  • FIG. 3 is a part-sectional side-elevational view of the grab.
  • FIG. 1 there is shown a paving machine comprising a vehicle 1 with a swivelling crane 2, to the jib 3 of which is secured, by suspension means 4, a grab 5.
  • FIG. 1 shows the machine with the vehicle 1 on a part B already paved and a stack of units 6 of stones or bricks arranged in a particular pattern, one of the units 6 being engaged by grab 5 and positioned in contiquity with the part B already paved in spaced relationship over sand bed Z.
  • grab 5 comprises a carrier frame 7 carrying a hand rail 8 and a supporting rail 9 and a supporting plate 10 adjustable in height, and by means of which a unit of stones or bricks 6 can be positioned.
  • the carrier frame 7 also carries four clamping strips 11, 12, 13, and 14, of which in the embodiment shown, strips 11 and 12 are rigidly secured to the carrier frame 7, while strips 13 and 14 are hinged to the carrier frame and are equipped with hydraulic actuating cylinders 15 and 16, respectively.
  • the operative surfaces of the hinging clamping strips 13 and 14 may be covered with a plurality of rubber elements 13a and 14a, respectively, which on the side facing the stones or bricks are provided with wear-resistant steel strips for protection of the rubber. In this way the grab can take up dimensional tolerances of the bricks.
  • the hydraulic system for the actuation of cylinders 15 and 16 may be arranged so that when clamping strips 13, 14 are closed, first cylinder 16 is actuated, and cylinders 15 are not actuated until after clamping strip 14 exerts a certain force on the group of stones or bricks 6.
  • the group of stones or bricks is thus first compressed in the longitudinal direction between strips 12 and 14 before being clamped by strips 11 and 13 as well.
  • the clamping is sufficiently great for the group of stones or bricks to be manoeuvred without the stones or bricks being shifted relatively to each other.
  • the hydraulic cylinders 15, 16 are actuated all at the same time, so that strips 13 and 14 are opened at the same time and all stones or bricks may fall simultaneously.
  • a hold-down mechanism for the border stones or bricks which presses these vertically downwardly onto the sand bed Z as the clamping strips are opened.
  • the hold-down mechanism comprises a tensioning frame 17 that can be moved up and down relatively to carrier frame 7 by a cylinder 18 via levers 18a. From the tensioning frame 17, a plurality of springs 19a extend downwardly and are attached to the carrier frame 7, and a plurality of connection rods 30 extend downwardly to separate hold-down strips 19 extending along the inside of the clamping strips 11-14.
  • the grab 5 is attached to the jib 3 by suspension means including, in the embodiment shown, a universal joint, such as a cardan joint 20, 24, at each end with a freewheel joint, such as a sliding sleeve unit 23 with spring rings 23a between them.
  • the freewheel joint 23 in the suspension prevents the transmission of minor vertical movements and vibrations of the crane jib to the unit of stones or bricks as it is being laid on the substrate and as it is being picked up from a stack of such units.
  • the spring means 23a function as a buffer during the hoisting of the grab.
  • the suspension arrangement makes it possible for the grab to be optimally adjusted relatively to a stack of units of stones or bricks, relatively to the substrate, and relatively to pavement already laid.
  • the suspension means may include a swivel joint 21 with a lock 22 against rotation, with which pre-selected settings relative to the crane jib can be rapidly accomplished.
  • the method and the grab for use therein, according to the invention make it possible for units or groups of bricks or stones to be positioned in a reliable manner without disturbing the herringbone bond with rectangular concrete paving stones, so that the subsequent insertion of half bricks becomes superfluous.
  • the release of a positioned unit of stones or bricks it is ensured that all stones or bricks thereof fall vertically downwardly on the sand bed, and the carefully prepared sand bed is not previously disturbed.
